Ray J: My New Puppy Almost Died!! And It Cost Me A Fortune

EXCLUSIVE

Ray J and Princess Love's time as puppy parents has been anything but easy ... their pooch almost died a week after they brought it home.

We're told the couple rushed Louie the Chihuahua to a NY animal hospital Thursday morning with a 105 degree fever. Louie had pneumonia and almost didn't make it through the night. Ray J dropped $6k on emergency treatment.

A worker at the pet store says the dog got a clean bill of health from a vet before the sale, and blames the illness on the stress of moving to a new home.

Lucky for Ray J and the dog ... Louie's expected to make a full recovery.
